Effectively improve the quality of print film

plus angle refers to the acute angle of the angle between the central line and the horizontal line. When printing in monochrome, 45 degree plus angle is often used, and the visual effect is the best. In multicolor overprint, moire fringes will be produced due to the regular superposition of points. The way to avoid the generation of moire fringes is to try to use the plus angle with the largest difference for four-color printing film to obtain a more correct composite action. Generally, four-color printing mostly places the main tone at 45 degrees, and the plus angle of other colors, but in the metallurgical industry, the difference is 30 degrees:

for originals dominated by characters, people's observation center is mainly on the face, and they are very sensitive to the differences in face color and level, Magenta should be set as the main hue, and the plus angle should be set to 45 degrees. CMYK is taken as 15, 45, 90 and 75 in turn

for the manuscript based on scenery, the hue is mainly green. The angle of cyan should be set to 45 degrees to reveal the picture characteristics of the beautiful mountains and rivers of nature. The angle of other colors is arranged as follows: CMYK takes 45, 15, 90, 75 in turn. Although setting the angle of the main tone can help to express the main features of the original, it is important to use an appropriate color sequence when printing If the main color is not printed in a later position, "Bert added, the color of the back printing will be reduced by 24.33% year-on-year, and the color will cover it, which is caused by the opacity of the ink

making print film is only the first step of high-quality pad printing and silk printing. We should attach great importance to it. Now Laser Phototypesetting Technology has been popularized in offset printing, gravure printing, flexographic printing and other mainstream printing processes, and has begun to extend to the special printing industry. Mastering the traditional print film production technology will lay the foundation for the adoption of new technologies in the future
